2-2-3 Work Schedule

The 2-2-3 schedule spreads 24/7 coverage across four crews working twelve-hour shifts. Each crew follows a fourteen-day cycle: two days on, two off, three on, two off, two on, three off. Week one contains three working days and week two contains four, so the pattern averages 42 hours a week. Two crews cover days and two cover nights, and crews usually swap between day and night rotation every two to four weeks to distribute the night burden evenly.

The signature benefit is the recurring three-day weekend every second week, and no crew ever works more than three consecutive days. That predictability is why it is standard in manufacturing, healthcare, emergency services, utilities, data centres, security operations centres and 24/7 customer support.

For employees, the attraction is fewer commutes, long stretches of consecutive time off, and a fixed pattern that can be planned against months ahead. For employers, coverage is continuous with a small number of handovers, and the alternating three-day break tends to support retention in roles where night work otherwise drives turnover.

Against that, twelve-hour shifts carry real fatigue risk, with error and incident rates rising in the final hours, particularly on nights. Rotating between days and nights disrupts circadian rhythm, and childcare that runs on a standard week fits a rotating twelve-hour pattern badly. Mitigations that work: forward rotation from days to nights rather than backwards, rest breaks scheduled rather than left to the shift, bright-light management on night crews, and a minimum 24-hour break when direction flips.

Under US federal law, overtime is owed on hours over 40 in a workweek, so a 2-2-3 pattern produces roughly 36 hours in one week and 48 in the next, generating eight overtime hours every second week unless the employer adopts a fixed 14-day 8/80 arrangement — available only to hospitals and residential care facilities — or a negotiated alternative workweek schedule where state law permits. California adds daily overtime after eight hours and double time after twelve, which makes an unmodified twelve-hour rotation considerably more expensive there.

Internationally the pattern has to be checked against working time rules before it is rolled out. The EU Working Time Directive caps the average week at 48 hours including overtime and requires 11 hours of daily rest, which a 2-2-3 rotation satisfies but which constrains how shifts can be swapped. India's state shops and establishments acts set daily caps around nine hours with double-time overtime, and the Philippines requires a night-shift differential of at least 10% for hours worked between 10pm and 6am.
